I am pleased to submit to you the 1967 Operating Summary for the Belleville
Water Pollution Control Plant, OWRC Project No. 2-0084-61.

The summary reviews progress during the year, outlines operating prob-
lems encountered and summarizes in graphs, charts and tables all sig-
nificant flow and cost data.

FOREWORD

• This operating summary has been prepared in
order to acquaint readers with the management of
the project during 1967. The efficiency of the
plant's operation is reflected in a general review.
Significant financial details are recorded, and
technical performance is illustrated by graphs and
charts.

The summary should answer two salient questions .
Are the project's facilities adequate at this time?
And can the project meet future requirements?

The Regional Operations Engineer is primarily
responsible for the preparation of the report, and
will be pleased to answer any questions regarding
it.

Most of the material for the graphs and charts was
compiled by the statistics section of the Division
of Plant Operations, with the final versions of the
graphs being drawn by the draughting section of the
Division of Sanitary Engineering. Cost data were
provided by the Division of Finance.

It will be evident from the report that all of these
groups co-operated with substantial success.

REVIEW

The Belleville Water Pollution Control Plant treated a total of 2396 million
gallons of sewage in 1967. This represents an average daily flow of 6. 56
million gallons per day.

The operating cost was $55, 314. 58. This exceeded the 1966 operating cost
by approximately $3,650, but was some $3,400 less than the budgeted a-
mount due to a delay in hiring a mechanic operator.

High flows were again received at the plant in 1967. The average daily
flow was over twice the design flow of 3 mgd. The highest flows were
registered during the months of February, March, April, November and
December.

Considerable mechanical trouble with the air blowers was experienced .
Two new impellers were needed for one blower and minor repairs were
done on the other.

The No. 4 pump at the Front Street pumping station continued to give
trouble and it was necessary to replace the sleeves and bearings. With
actual flows much greater than the design flow, the pumping head exceed-
ed the design head, thus straining the pumping equipment abnormally.

The boiler controls were altered to provide automatic operation. Previ-
ously the boiler could automatically switch from gas to oil, but not the
reverse. The new controls made switching over both ways automatic.

An addition to the staff, Mr. R. Grey, was engaged in May, as a mechanic
operator.

The plant was inspected by head office personnel several times during the
year and found to be in satisfactory condition. A feeling of teamwork was
evident among the plant staff members, which no doubt aided in the pre-
sent efficient operation.

PROBABILITY OF FLOWS

The 1967 probability of flow graph shows that the flow increased sub-
stantially. A flow of 6. 6 mgd was received 50 percent of the time. Twice
the design flow of 3. 0 mgd was received 83 percent of the time.

DAILY FLOWS

The daily flow plot shows very little variation, with the flows fluctuating
near the 6. 0 mgd level.

COMMfNTS

In 1967, ten, eight-hour composite samples were collected from the plant influent
and effluent and submitted to the OWRC Laboratory for analysis. The results of
these analyses indicate that the average BOD of the influent was 117 ppm and the
average SS of the influent was 185 ppm. The results of the effluent analyses indicate
an average BOD of 38 ppm and a SS of 84 ppm. This represents a BOD reduction of
59% and a SS reduction of 66. 5%.

A total of 947 tons of BOD and 1474 tons SS was removed from the sewage in 1967 .
These figures show a considerable increase from the 1966 figures.

The total quantity of grit removed at the plant in 1967 was 945 cubic feet, 400 cubic
feet less than that received in 1966.

For a primary treatment plant the removals stated above are satisfactory. 17

In 1967, a total of 4, 588, 554 gallons of sludge was pumped to the digesters with
a total solids concentration of 1. 47%. The quantity of sludge removed from the
digesters was 850, 624 gallons with total solids concentration averaging 9. 89%.
This represents a reduction in volume of 81. 5%

The gas produced from the sludge decomposed in the digesters amounted to
' 66, 061, 200 cubic feet.

COMMENTS

Chlorination is practised at the Belleville Water Pollution Control Plant to disinfect
the final effluent from the plant before it is discharged into the Bay of Quinte .
Chlorination commenced on May 17, and was discontinued on November 15„ A total
of 29, 945 pounds of chlorine was used to obtain a chlorine residual of 0. 5 ppm after
fifteen minutes of contact.

RECOMMENDATIONS

The City of Belleville should continue its program to remove storm water
from the sanitary sewer system.
